Electricity

Electricity is a steady flow of Negative Charges traveling toward the Positive Charges.

A Circuit is a path where Negative Charges can flow toward Positive Charges.

Conductors and Insulators

Conductors are materials that allow Negative Charges to flow through.

Insulators are materials that stop the flow of Negative Charges.

All Metals are Conductors while all Non Metals are Insulators.

Switch

A Switch is a device used to control the flow of negative charges through a circuit.

OFF- The Switch is OPEN to stop the flow of Negative Charges through the circuit toward the Positive Charges.

ON - The Switch is CLOSED to allow the flow of Negative Charges through the circuit toward the Positive Charges.
